Abstract:
A filter catalyst of the present invention is comprised of a catalyst-supporting substrate 1, and catalytic portions 5, 6 for purifying an exhaust gas. The catalytic portions includes the first catalytic portion 5 for purifying HC, CO and NOx, and the second catalytic portion 6 for purifying the particulates. The first catalytic portion 5 is formed on a surface of at least a portion of the cellular wall 40, and the second catalytic portion 6 is formed on an inside surface of the pores. In the filter catalyst of the present invention purifying ability of the exhaust gas is increased, and the filter catalyst of the present invention can suppress rise of the pressure loss of the exhaust gas.
